Here we will present recent results of two kinds of graphene based smart materials for civil engineering. Smart cement material with compression sensibility was prepared by adding different dosages of graphene in the mixture of cement. The electrical properties and the compression sensibility of the smart material were systemically investigated. In addition, the properties of the graphene/cement composite within the different cement hydration ages, the effects of graphene species were also discussed. The results indicated that this smart cement material is a promising candicate for the application of the intelligent structures. Multifunctional films based on graphene were prepared by a facile spray coating method. The electrical properties, strain sensing performance and the photocatalytic performance the multifunctional films were systematically investigated. The graphene based film has potential in many applications, such as transparent conductive films, strain sensors, photocatalytic self-cleaning and protective coatings in fields of medical, sport care and civil engineering structural health monitoring.
